How thick can the sprayer spray fireproof paint at one time

The ** of the spraying machine is about a few thousand yuan per unit, the cheap one is one or two thousand yuan, and the expensive one is one or two thousand yuan. The ** of spraying machine is affected by many aspects, such as brand, category, specification, market, etc. The key is to learn how to choose.

1. The performance of the equipment, for the powder spraying equipment, is mainly the powder rate, the powder capacity, the processing capacity of complex workpieces, this indicator is difficult for friends to understand for the first time, we must carefully understand, carefully compare the powder capacity of the high-pressure built-in electrostatic spraying machine is much higher than that of high-pressure external products, and the performance of similar products of different manufacturers often has a large gap; The performance of the spray gun cannot be understood only by asking about relevant parameters such as electrostatic voltage, charging current, etc., which cannot be verified by the user and are often false, so it must be done through obvious special work...

Spraying fireproof coatings, thick and thin, the machines used are not the same, thick fireproof coatings are generally in 2 cm, thin in two or three millimeters, the models used are not the same, thick fireproof coatings can generally be sprayed 100 square meters per hour, thin can generally do 300 square meters per hour, contact me for technical exchanges.

2 to 3 square meters of spraying material in one hour, calculated according to spraying 1cm, 200-300 square meters can be brushed in one hour.

Fireproof coatings are divided into ultra-thin, thin and thick, depending on which one you spray, you say I am good to you.

Generally, the thickness of the airless sprayer depends on your spraying technique and the diameter of the nozzle, which can be thick or thin.

Look at the speed of the gun, generally 1-3 mm.

Looking back at the twilight is how the sunset contacted you,

It depends on your level of operation and the speed of the gun, I use the san qi s3, over and over again in the millimeter.

According to the national standard construction specifications, the thickness of the thick fireproof coating needs to reach more than 15mm, and the fireproof needs to be sprayed about 25mm-30mm within normal hours. If you need to use thick fireproof coatings for civil engineering, choose Yikun fire protection, the company's products are directly supplied by manufacturers, which are affordable and accept the public package of materials, saving time and effort for customers.

Thick fireproof coating needs to be sprayed about 25mm-30mm for fireproof within hours, and the coating is one of the thick-coated building fireproof coatings. Thick fireproof coatings are made of inorganic flame retardant and heat-insulating materials such as desulfurization gypsum. The product has the characteristics of strong corrosion resistance, high compressive strength, good water resistance, light specific gravity, long fire resistance time, etc., the use of this coating can greatly reduce the weight of the fireproof coating compared with the cement-based fireproof coating, and the superior anti-corrosion performance of this coating can be exempted from anti-corrosion construction, and is suitable for the fire protection of indoor steel structure buildings with high fire resistance limit requirements such as gymnasiums, terminal buildings, and large workshops.

Jikun fire prevention has sophisticated production equipment and sophisticated testing instruments"Integrity-based, brave to climb new heights, excellence, the pursuit of excellence"The sixteen-character policy, dedicated to providing customers with high-quality products and satisfactory service.

According to the requirements of GB14907-2018 specification, the thickness of the coating (non-intumescent fire retardant coating) is greater than 15mm.

At present, the major fire retardant coating production companies have thick non-intumescent fire retardant coating thickness between 15-50mm.

The detailed construction thickness is constructed according to the product inspection report and project design requirements.

Indoor non-intumescent steel structure fire retardant coatings (thick fire retardant coatings) have a fire resistance time of hours, according to the new inspection report and trend coating thickness between 25-30 mm.

Indoor non-intumescent steel structure fireproof coating (thick fireproof coating) has a small fire-resistant time and a coating thickness of millimeters. Reference dosage 12 kg sqm.

Dear, hello, I am glad to answer for you that the hourly spray standard of thick fireproof coating should be: hourly fire resistance limit thickness; Hour fire resistance limit thickness; Hour fire resistance limit thickness; Hourly fire resistance limit thickness Steel structure fireproof coatings are ultra-thin, thin, and thick, hourly brushing thickness, hourly brushing thickness, and 1-hour brushing thickness. The fire protection principle of fire retardant coatings can be roughly summarized into the following five points:

The fire retardant coating itself is flame retardant or non-combustible, so that the protected substrate does not come into direct contact with the air, delaying the object to catch fire and reducing the rate of combustion. In addition to being inherently flame retardant or non-combustible, fire retardant coatings also have a low thermal conductivity, which can delay the transfer of flame temperature to the substrate to be protected. The fireproof coating is heated to decompose non-combustible inert gas, dilute the flammable gas decomposed by the heat of the protected object, making it less flammable or slowing down the burning rate.

The nitrogen-containing fire retardant coating is heated to decompose NO, NH3 and other groups, which are combined with organic free radicals to interrupt the chain reaction and reduce the temperature. The intumescent fire retardant coating expands and foams when heated, forming a carbonaceous foam insulation layer to seal the protected object, delay the transfer of heat to the substrate, and prevent the object from catching fire and burning or reducing its strength due to the increase in temperature.

Thick fireproof coating is sprayed 30 per hour.

According to the national standard, the thick layer of fire retardant paint is about 15 mm or more, and if it is applied for two and a half hours, the thickness needs to reach 25 to 30 mm.

In addition, the fire retardant coating is too thick, which not only needs to be mixed with mortar on site, but also layered to ensure the adhesion of its surface.

Precautions for the construction of fire retardant coatings:

1. Before the fireproof coating is painted, the surface of the object should be wiped clean and clear, so that it is dust-free and oil-free. If the interior of the room is coated with fireproof paint, the walls, windows and other objects should be covered and protected.

2. Before spraying, the object should be brushed all over the interface agent, and then the fireproof coating should be applied after the interface agent is dry, so that it is convenient to paint and not flow. If it's a large steel. In addition, the consistency of the interface agent is related to the coating method, and usually, a steel frame mesh is added to prevent the paint from falling off.

3. The fireproof coating is usually sprayed with a concave-convex bucket spray gun, and the pressure is to. The muzzle diameter is 6 to 10 mm and is perpendicular to the surface being painted. In addition, the first spray should not be too thick, and the next coat can only be applied until it is dry. <>

Ultra-thin or thin fireproof coatings can use high-pressure airless sprayers, thick steel structure fireproof coatings can only use low-pressure air sprayers in mind, high-pressure airless sprayers and low-pressure air sprayers can spray fireproof coatings, but high-pressure airless sprayers can spray fireproof coatings that have no particles in the paint, no fibers, and will not quickly cure the coating, which is mainly related to the spraying principle of the machine. The low-pressure air sprayer can be used to spray thick steel structure fireproof coatings, which fireproof coatings can be sprayed by the spraying machine, mainly depending on the paint used in their construction, it is best to use the machine to test the paint they want to spray.

Summary. The following is my <> kiss to your question of [one centimeter thick, how many square meters can be sprayed with fireproof paint in one meal], hello! One centimeter thick, fireproof coating can spray 70-150 square meters, thick steel structure fireproof coating is a lightweight, heat-insulating fireproof coating, due to low density, small volume; And it has strong adhesion and good construction workability; Excellent acid and alkali resistance, usually protect the steel structure from the erosion and weathering of environmental factors, not easy to chalk and other advantages, a ton of thick steel structure fireproof coating can be used about 70-150 square meters, but also need more steel structure fire resistance calculation usage.

Relatives and friends, fireproof coating spraying should be completed in several layers, a large layer of spraying to basically cover the surface of the steel, and then each layer of spraying thickness of 5 10mm is generally about 7mm. After each layer of coating is basically dry or cured, the next layer of paint can be sprayed, usually every day. The spraying protection method, the number of coats sprayed and the thickness of the coating should be determined according to the fire protection design requirements.

When spraying, the spray gun should be perpendicular to the surface of the steel component to be sprayed, the spray distance should be 6 10m, and the spraying air pressure should be kept at. The running speed of the spray gun should be stable and not stay in the same position for a long time to avoid causing paint to accumulate and flow. During the spraying process, the batching and feeding into the spraying machine should be carried out continuously without pause.

During the construction process, the operator should use a thickness gauge needle to detect the thickness of the coating until it meets the thickness specified in the design, and then stop spraying.

Summary. Thin fire-retardant coatings can be made with fighter guns or spiral extrusion pumps.

Spiral extrusion pumps are the fastest, but they are wasteful of fire-retardant paint. It is suitable for the construction of large components.

The fighter spray gun method requires manual loading. It is more time-consuming, but it saves materials. Smaller components are more appropriate.

According to the characteristics of the project, you can choose the appropriate construction technology.
